To reduce the tube side pressure drop for the same flow rate, the heat exchanger recommended is _______________?
Correct answer: C. 1-1 heat exchanger
- A. 1-2 heat exchanger
- B. 3-2 heat exchanger
- C. 1-1 heat exchanger
- D. 2-4 heat exchanger
Explanation
A 1-1 exchanger has only one tube-side pass, so the same flow is distributed through a longer flow area with lower velocity and pressure drop than in multipass arrangements.
